My friend Google has been of no help, and my searches through the bluez source have not found what I was looking for: information, and ideally source code, for the Bluetooth encryption algorithms. I'm trying to create a simple Bluetooth stack for RISC OS. Rather than attempt to port an existing open source stack, I'm trying to write from scratch as far as possible. This may be a naive idea, but I want to do it as much for the educational value to me as for the end product. I have been able to perform an inquiry, get the names of discoverable devices, and perform the first step of pairing. So far, so good - and, yes, that's the easy stuff. So if anyone can point me to sources of information detailed and explicit enough to show me how Bluetooth encryption and decryption are done, I would very much appreciate it. I have the Bluetooth core specification, but I'm not confident that I can implement correctly from it alone. I'm also looking for test data, ideally for each step through each algorithm. If there is a book that covers the subject in enough detail, I'd be happy to buy it.
